Keep it the way it is. Barn doors are for barns.

You do not have room on the wall for a sliding door for either doorway. Barn doors are not privacy doors. They do not fit tight enough to the wall for that. Leave the doors you have. Your bedroom door is like many others. If you want pictures there, put them there, and when you are in your room with the door shut, you will be able to view them.

No sliding door with children. Fingers caught, etc. If you really and truly never need privacy in your bedroom just remove the door and store it.

i agree do not do a barn door. show us a picture of the full wall on which you want to put photos.

This is the wall outside my bedroom I want to add a door

there is a wall in your primary bedroom where you want to put photos. when you have time, post a picture of that wall. i bet people here can help you with photo placement that does not require losing your bedroom door.

Here is the whole wall

Is there there anything else in the gray hallway? Closet??
What is this?

I actully have no idea what you want to do. Barn doors do not provide privacy but I need to see a floor plan to understand what you want to do. The dollhouse space is what? A play room or a bedroom?The wall next to the door in your bedroom ha to open somewhere so maybe move the rdresser and the desk to another spot or hang art above the desk I really do not understand the issue

It looks to me like you have a lot of wall space above the dresser and ab0ve the desk. How many photos do you want to hang, and how big are they?

You also have an enormous empty wall in the hallway leading to the bedroom (a great space for photos, IMO), and an even bigger wall in the room with the dollhouse.
